INTRODUCTION

Wireless communication networks are widely deployed to provide variouscommunication services such as voice, video, packet data, messaging,broadcast, and the like. These wireless networks may be multiple-accessnetworks capable of supporting multiple users by sharing the availablenetwork resources. Such networks may be multiple access networks thatsupport communications for multiple users by sharing the availablenetwork resources.

A wireless communication network may include several components. Thesecomponents may include wireless communication devices, such as networkentities base stations (e.g., base stations or node Bs) that may supportcommunication for a number of user equipments (UEs). A UE maycommunicate with a network entity via downlink and uplink. The downlink(or forward link) refers to the communication link from the networkentity to the UE, and the uplink (or reverse link) refers to thecommunication link from the UE to the network entity.

A network entity may transmit data and control information on a downlinkto a UE or may receive data and control information on an uplink fromthe UE. On the downlink, a transmission from the network entity mayencounter interference due to transmissions from neighbor networkentities or from other wireless radio frequency (RF) transmitters. Onthe uplink, a transmission from the UE may encounter interference fromuplink transmissions of other UEs communicating with the neighbornetwork entities or from other wireless RF transmitters. Thisinterference may degrade performance on both the downlink and uplink.

As the demand for mobile broadband access continues to increase, thepossibilities of interference and congested networks grows with more UEsaccessing the long-range wireless communication networks and moreshort-range wireless systems being deployed in communities. Research anddevelopment continue to advance wireless technologies not only to meetthe growing demand for mobile broadband access, but to advance andenhance the user experience with mobile communications.

DETAILED DESCRIPTION

The detailed description set forth below, in connection with theappended drawings, is intended as a description of variousconfigurations and is not intended to limit the scope of the disclosure.Rather, the detailed description includes specific details for thepurpose of providing a thorough understanding of the inventive subjectmatter. It will be apparent to those skilled in the art that thesespecific details are not required in every case and that, in someinstances, well-known structures and components are shown in blockdiagram form for clarity of presentation.

The present disclosure provides systems, apparatus, methods, andcomputer-readable media that support adaptable configuration forperiodic and semi-persistent layer 1 (L1) measurement reporting.Particular implementations of the subject matter described in thisdisclosure may be implemented to realize one or more of the followingpotential advantages or benefits. In some aspects, the presentdisclosure provides techniques for adaptable configuration for periodicand semi-persistent L1 measurement reporting. The ability of either a UEor network entity to dynamically request modification of the L2measurement reporting operations allows more flexibility in reportingand opportunity for more efficient use of communication resources. Forexample, where communication with a higher priority UE may be delayedbecause of uplink beam reservation for a periodic or semi-persistentreporting occasion, the network entity may request a modification in theconfigured reporting occasions in order to more efficiently serve thehigher-priority UE. Additionally, when no new information would be sentin a measurement report, the UE may request a modification that skips orcancels those reporting occasions in order to reduce unnecessary payloador unnecessary use of resources.

This disclosure relates generally to providing or participating inauthorized shared access between two or more wireless devices in one ormore wireless communications systems, also referred to as wirelesscommunications networks. In various implementations, the techniques andapparatus may be used for wireless communication networks such as codedivision multiple access (CDMA) networks, time division multiple access(TDMA) networks, frequency division multiple access (FDMA) networks,orthogonal FDMA (OFDMA) networks, single-carrier FDMA (SC-FDMA)networks, LTE networks, GSM networks, 5^(th) Generation (5G) or newradio (NR) networks (sometimes referred to as “5G NR” networks, systems,or devices), as well as other communications networks. As describedherein, the terms “networks” and “systems” may be used interchangeably.

A CDMA network, for example, may implement a radio technology such asuniversal terrestrial radio access (UTRA), cdma2000, and the like. UTRAincludes wideband-CDMA (W-CDMA) and low chip rate (LCR). CDMA2000 coversIS-2000, IS-95, and IS-856 standards.

A TDMA network may, for example implement a radio technology such asGlobal System for Mobile Communication (GSM). The 3rd GenerationPartnership Project (3GPP) defines standards for the GSM EDGE (enhanceddata rates for GSM evolution) radio access network (RAN), also denotedas GERAN. GERAN is the radio component of GSM/EDGE, together with thenetwork that joins the base stations (for example, the Ater and Abisinterfaces) and the base station controllers (A interfaces, etc.). Theradio access network represents a component of a GSM network, throughwhich phone calls and packet data are routed from and to the publicswitched telephone network (PSTN) and Internet to and from subscriberhandsets, also known as user terminals or user equipments (UEs). Amobile phone operator's network may comprise one or more GERANs, whichmay be coupled with UTRANs in the case of a UMTS/GSM network.Additionally, an operator network may also include one or more LTEnetworks, or one or more other networks. The various different networktypes may use different radio access technologies (RATs) and RANs.

An OFDMA network may implement a radio technology such as evolved UTRA(E-UTRA), Institute of Electrical and Electronics Engineers (IEEE)802.11, IEEE 802.16, IEEE 802.20, flash-OFDM and the like. UTRA, E-UTRA,and GSM are part of universal mobile telecommunication system (UMTS). Inparticular, long term evolution (LTE) is a release of UMTS that usesE-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documentsprovided from an organization named “3rd Generation Partnership Project”(3GPP), and cdma2000 is described in documents from an organizationnamed “3rd Generation Partnership Project 2” (3GPP2). These variousradio technologies and standards are known or are being developed. Forexample, the 3GPP is a collaboration between groups oftelecommunications associations that aims to define a globallyapplicable third generation (3G) mobile phone specification. 3GPP LTE isa 3GPP project which was aimed at improving UMTS mobile phone standard.The 3GPP may define specifications for the next generation of mobilenetworks, mobile systems, and mobile devices. The present disclosure maydescribe certain aspects with reference to LTE, 4G, or 5G NRtechnologies; however, the description is not intended to be limited toa specific technology or application, and one or more aspects describedwith reference to one technology may be understood to be applicable toanother technology. Additionally, one or more aspects of the presentdisclosure may be related to shared access to wireless spectrum betweennetworks using different radio access technologies or radio airinterfaces.

5G networks contemplate diverse deployments, diverse spectrum, anddiverse services and devices that may be implemented using an OFDM-basedunified, air interface. To achieve these goals, further enhancements toLTE and LTE-A are considered in addition to development of the new radiotechnology for 5G NR networks. The 5G NR will be capable of scaling toprovide coverage (1) to a massive Internet of things (IoTs) with anultra-high density (e.g., ˜1 M nodes/km²), ultra-low complexity (e.g.,˜10 s of bits/sec), ultra-low energy (e.g., ˜10+ years of battery life),and deep coverage with the capability to reach challenging locations;(2) including mission-critical control with strong security to safeguardsensitive personal, financial, or classified information, ultra-highreliability (e.g., ·99.9999% reliability), ultra-low latency (e.g., ˜1millisecond (ms)), and users with wide ranges of mobility or lackthereof; and (3) with enhanced mobile broadband including extreme highcapacity (e.g., ˜10 Tbps/km²), extreme data rates (e.g., multi-Gbpsrate, 100+ Mbps user experienced rates), and deep awareness withadvanced discovery and optimizations.

Devices, networks, and systems may be configured to communicate via oneor more portions of the electromagnetic spectrum. The electromagneticspectrum is often subdivided, based on frequency or wavelength, intovarious classes, bands, channels, etc. In 5G NR two initial operatingbands have been identified as frequency range designations FR1 (410MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). The frequencies between FR1and FR2 are often referred to as mid-band frequencies. Although aportion of FR1 is greater than 6 GHz, FR1 is often referred to(interchangeably) as a “sub-6 GHz” band in various documents andarticles. A similar nomenclature issue sometimes occurs with regard toFR2, which is often referred to (interchangeably) as a “millimeter wave”(mmW) band in documents and articles, despite being different from theextremely high frequency (EHF) band (30 GHz-300 GHz) which is identifiedby the International Telecommunications Union (ITU) as a “mmW” band.

The frequencies between FR1 and FR2 are often referred to as mid-bandfrequencies. Recent 5G NR studies have identified an operating band forthese mid-band frequencies as frequency range designation FR3 (7.126GHz-24.25 GHz). Frequency bands falling within FR3 may inherit FR1characteristics and/or FR2 characteristics, and, thus, may effectivelyextend features of FR1 and/or FR2 into mid-band frequencies. Inaddition, higher frequency bands are currently being explored to extend5G NR operation beyond 52.6 GHz. For example, three higher operatingbands have been identified as frequency range designations FR2x (52.6GHz-71 GHz), FR4 (71 GHz-114.25 GHz), and FR5 (114.25 GHz-275 GHz). Eachof these higher frequency bands falls within the EHF band.

With the above aspects in mind, unless specifically stated otherwise, itshould be understood that the term “sub-6 GHz” or the like if usedherein may broadly represent frequencies that may be less than 6 GHz,may be within FR1, or may include mid-band frequencies. Further, unlessspecifically stated otherwise, it should be understood that the term“mmW” or the like if used herein may broadly represent frequencies thatmay include mid-band frequencies, may be within FR2, FR2x, FR4, and/orFR5, or may be within the EHF band.

5G NR devices, networks, and systems may be implemented to use optimizedOFDM-based waveform features. These features may include scalablenumerology and transmission time intervals (TTIs); a common, flexibleframework to efficiently multiplex services and features with a dynamic,low-latency time division duplex (TDD) design or frequency divisionduplex (FDD) design; and advanced wireless technologies, such as massivemultiple input, multiple output (MIMO), robust mmW transmissions,advanced channel coding, and device-centric mobility. Scalability of thenumerology in 5G NR, with scaling of subcarrier spacing, may efficientlyaddress operating diverse services across diverse spectrum and diversedeployments. For example, in various outdoor and macro coveragedeployments of less than 3 GHz FDD or TDD implementations, subcarrierspacing may occur with 15 kHz, for example over 1, 5, 10, 20 MHz, andthe like bandwidth. For other various outdoor and small cell coveragedeployments of TDD greater than 3 GHz, subcarrier spacing may occur with30 kHz over 80/100 MHz bandwidth. For other various indoor widebandimplementations, using a TDD over the unlicensed portion of the 5 GHzband, the subcarrier spacing may occur with 60 kHz over a 160 MHzbandwidth. Finally, for various deployments transmitting with mmWcomponents at a TDD of 28 GHz, subcarrier spacing may occur with 120 kHzover a 500 MHz bandwidth.

The scalable numerology of 5G NR facilitates scalable TTI for diverselatency and quality of service (QoS) requirements. For example, shorterTTI may be used for low latency and high reliability, while longer TTImay be used for higher spectral efficiency. The efficient multiplexingof long and short TTIs to allow transmissions to start on symbolboundaries. 5G NR also contemplates a self-contained integrated subframedesign with uplink or downlink scheduling information, data, andacknowledgement in the same subframe. The self-contained integratedsubframe supports communications in unlicensed or contention-basedshared spectrum, adaptive uplink or downlink that may be flexiblyconfigured on a per-cell basis to dynamically switch between uplink anddownlink to meet the current traffic needs.

For clarity, certain aspects of the apparatus and techniques may bedescribed below with reference to example 5G NR implementations or in a5G-centric way, and 5G terminology may be used as illustrative examplesin portions of the description below; however, the description is notintended to be limited to 5G applications.

Moreover, it should be understood that, in operation, wirelesscommunication networks adapted according to the concepts herein mayoperate with any combination of licensed or unlicensed spectrumdepending on loading and availability. Accordingly, it will be apparentto a person having ordinary skill in the art that the systems, apparatusand methods described herein may be applied to other communicationssystems and applications than the particular examples provided.

While aspects and implementations are described in this application byillustration to some examples, those skilled in the art will understandthat additional implementations and use cases may come about in manydifferent arrangements and scenarios. Innovations described herein maybe implemented across many differing platform types, devices, systems,shapes, sizes, packaging arrangements. For example, implementations oruses may come about via integrated chip implementations or othernon-module-component based devices (e.g., end-user devices, vehicles,communication devices, computing devices, industrial equipment, retaildevices or purchasing devices, medical devices, AI-enabled devices,etc.). While some examples may or may not be specifically directed touse cases or applications, a wide assortment of applicability ofdescribed innovations may occur. Implementations may range fromchip-level or modular components to non-modular, non-chip-levelimplementations and further to aggregated, distributed, or originalequipment manufacturer (OEM) devices or systems incorporating one ormore described aspects. In some practical settings, devicesincorporating described aspects and features may also necessarilyinclude additional components and features for implementation andpractice of claimed and described aspects. It is intended thatinnovations described herein may be practiced in a wide variety ofimplementations, including both large devices or small devices,chip-level components, multi-component systems (e.g., radio frequency(RF)-chain, communication interface, processor), distributedarrangements, end-user devices, etc. of varying sizes, shapes, andconstitution.

FIG. 1 illustrates an example of a wireless communications system 100that supports scheduling requests for spatial multiplexing in accordancewith one or more aspects of the present disclosure. Wirelesscommunications system 100 may include one or more network entities 105,one or more UEs 115, and a core network 130. In some examples, wirelesscommunications system 100 may be a Long Term Evolution (LTE) network, anLTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR)network, or a network operating in accordance with other systems andradio technologies, including future systems and radio technologies notexplicitly mentioned herein.

Network entities 105 may be dispersed throughout a geographic area toform wireless communications system 100 and may include devices indifferent forms or having different capabilities. In 3GPP, the term“cell” may refer to this particular geographic coverage area of anetwork entity, such as network entities 105, or a network entitysubsystem serving the coverage area, depending on the context in whichthe term is used. In various examples, network entity 105 may bereferred to as a network element, a mobility element, a radio accessnetwork (RAN) node, or network equipment, among other nomenclature. Insome examples, network entities 105 and UEs 115 may wirelesslycommunicate via one or more communication links 125 (e.g., a radiofrequency (RF) access link). For example, network entity 105 may supporta coverage area 110 (e.g., a geographic coverage area) over which UEs115 and network entity 105 may establish one or more communication links125. Coverage area 110 may be an example of a geographic area over whichnetwork entity 105 and UE 115 may support the communication of signalsaccording to one or more radio access technologies (RATs).

UEs 115 may be dispersed throughout coverage area 110 of the wirelesscommunications system 100, and each UE 115 may be stationary, or mobile,or both at different times. UEs 115 may be devices in different forms orhaving different capabilities. Some example UEs 115 are illustrated inFIG. 1 . UEs 115 described herein may be able to communicate withvarious types of devices, such as other UEs 115 or network entities 105,as shown in FIG. 1 .

As described herein, a node of wireless communications system 100, whichmay be referred to as a network node, or a wireless node, may be networkentity 105 (e.g., any network entity described herein), UE 115 (e.g.,any UE described herein), a network controller, an apparatus, a device,a computing system, one or more components, or another suitableprocessing entity configured to perform any of the techniques describedherein. For example, a node may be UE 115. As another example, a nodemay be network entity 105. As another example, a first node may beconfigured to communicate with a second node or a third node. In oneaspect of this example, the first node may be UE 115, the second nodemay be network entity 105, and the third node may be UE 115. In anotheraspect of this example, the first node may be UE 115, the second nodemay be network entity 105, and the third node may be network entity 105.In yet other aspects of this example, the first, second, and third nodesmay be different relative to these examples. Similarly, reference to UE115, network entity 105, apparatus, device, computing system, or thelike may include disclosure of UE 115, network entity 105, apparatus,device, computing system, or the like being a node. For example,disclosure that UE 115 is configured to receive information from networkentity 105 also discloses that a first node is configured to receiveinformation from a second node.

In some examples, network entities 105 may communicate with core network130, or with one another, or both. For example, network entities 105 maycommunicate with the core network 130 via one or more backhaulcommunication links 120 (e.g., in accordance with an S1, N2, N3, orother interface protocol). In some examples, network entities 105 maycommunicate with one another over backhaul communication link 120 (e.g.,in accordance with an X2, Xn, or other interface protocol) eitherdirectly (e.g., directly between network entities 105) or indirectly(e.g., via core network 130). In some examples, network entities 105 maycommunicate with one another via a midhaul communication link 162 (e.g.,in accordance with a midhaul interface protocol) or a fronthaulcommunication link 168 (e.g., in accordance with a fronthaul interfaceprotocol), or any combination thereof. Backhaul communication links 120,midhaul communication links 162, or fronthaul communication links 168may be or include one or more wired links (e.g., an electrical link, anoptical fiber link), one or more wireless links (e.g., a radio link, awireless optical link), among other examples or various combinationsthereof. UE 115 may communicate with core network 130 through acommunication link 155.

One or more of network entities 105 described herein may include or maybe referred to as base station 140 (e.g., a base transceiver station, aradio base station, an NR base station, an access point, a radiotransceiver, a transmission-reception point (TRP), a NodeB, an eNodeB(eNB), a next-generation NodeB or a giga-NodeB (either of which may bereferred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a HomeNodeB, a Home eNodeB, or other suitable terminology). In some examples,network entity 105 (e.g., base station 140) may be implemented in anaggregated (e.g., monolithic, standalone) base station architecture,which may be configured to utilize a protocol stack that is physicallyor logically integrated within a single network entity 105 (e.g., asingle RAN node, such as base station 140).

In some examples, network entity 105 may be implemented in adisaggregated architecture (e.g., a disaggregated base stationarchitecture, a disaggregated RAN architecture), which may be configuredto utilize a protocol stack that is physically or logically distributedamong two or more network entities 105, such as an integrated accessbackhaul (IAB) network, an open RAN (O-RAN) (e.g., a networkconfiguration sponsored by the O-RAN Alliance), or a virtualized RAN(vRAN) (e.g., a cloud RAN (C-RAN)). For example, network entity 105 mayinclude one or more of a central unit (CU) 160, a distributed unit (DU)165, a radio unit (RU) 170, a RAN Intelligent Controller (RIC) 175(e.g., a Near-Real Time RIC (Near-RT RIC), a Non-Real Time RIC (Non-RTRIC)), a Service Management and Orchestration (SMO) 180 system, or anycombination thereof. RU 170 may also be referred to as a radio head, asmart radio head, a remote radio head (RRH), a remote radio unit (RRU),or a transmission reception point (TRP). One or more components ofnetwork entities 105 in a disaggregated RAN architecture may beco-located, or one or more components of the network entities 105 may belocated in distributed locations (e.g., separate physical locations). Insome examples, one or more network entities 105 of a disaggregated RANarchitecture may be implemented as virtual units (e.g., a virtual CU(VCU), a virtual DU (VDU), a virtual RU (VRU)).

The split of functionality between CU 160, DU 165, and RU 175 isflexible and may support different functionalities depending upon whichfunctions (e.g., network layer functions, protocol layer functions,baseband functions, RF functions, and any combinations thereof) areperformed at CU 160, DU 165, or RU 175. For example, a functional splitof a protocol stack may be employed between CU 160 and DU 165 such thatCU 160 may support one or more layers of the protocol stack and DU 165may support one or more different layers of the protocol stack. In someexamples, CU 160 may host upper protocol layer (e.g., layer 3 (L3),layer 2 (L2)) functionality and signaling (e.g., Radio Resource Control(RRC), service data adaption protocol (SDAP), Packet Data ConvergenceProtocol (PDCP)). CU 160 may be connected to one or more DUs 165 or RUs170, and one or more DUs 165 or RUs 170 may host lower protocol layers,such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radiolink control (RLC) layer, medium access control (MAC) layer)functionality and signaling, and may each be at least partiallycontrolled by CU 160.

Additionally, or alternatively, a functional split of the protocol stackmay be employed between DU 165 and RU 170 such that DU 165 may supportone or more layers of the protocol stack and RU 170 may support one ormore different layers of the protocol stack. DU 165 may support one ormultiple different cells (e.g., via one or more RUs 170). In some cases,a functional split between CU 160 and DU 165, or between DU 165 and RU170 may be within a protocol layer (e.g., some functions for a protocollayer may be performed by one of CU 160, DU 165, or RU 170, while otherfunctions of the protocol layer are performed by a different one of CU160, DU 165, or RU 170). CU 160 may be functionally split further intoCU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 maybe connected to one or more DUs 165 via midhaul communication link 162(e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs170 via fronthaul communication link 168 (e.g., open fronthaul (FH)interface). In some examples, midhaul communication link 162 orfronthaul communication link 168 may be implemented in accordance withan interface (e.g., a channel) between layers of a protocol stacksupported by respective network entities 105 that are in communicationover such communication links.

In wireless communications systems (e.g., wireless communications system100), infrastructure and spectral resources for radio access may supportwireless backhaul link capabilities to supplement wired backhaulconnections, providing an IAB network architecture (e.g., to corenetwork 130). In some cases, in an IAB network, one or more networkentities 105 (e.g., IAB nodes 104) may be partially controlled by eachother. One or more IAB nodes 104 may be referred to as a donor entity oran IAB donor. One or more DUs 165 or one or more RUs 170 may bepartially controlled by one or more CUs 160 associated with a donornetwork entity 105 (e.g., a donor base station 140). The one or moredonor network entities 105 (e.g., IAB donors) may be in communicationwith one or more additional network entities 105 (e.g., IAB nodes 104)via supported access and backhaul links (e.g., backhaul communicationlinks 120). IAB nodes 104 may include an IAB mobile termination (IAB-MT)controlled (e.g., scheduled) by DUs 165 of a coupled IAB donor. An IAB-MT may include an independent set of antennas for relay ofcommunications with UEs 115, or may share the same antennas (e.g., of RU170) of IAB node 104 used for access via DU 165 of IAB node 104 (e.g.,referred to as virtual IAB-MT (vIAB-MT)). In some examples, IAB nodes104 may include DUs 165 that support communication links with additionalentities (e.g., IAB nodes 104, UEs 115) within the relay chain orconfiguration of the access network (e.g., downstream). In such cases,one or more components of the disaggregated RAN architecture (e.g., oneor more IAB nodes 104 or components of IAB nodes 104) may be configuredto operate according to the techniques described herein.

For instance, an access network (AN) or RAN may include communicationsbetween access nodes (e.g., an IAB donor), IAB nodes 104, and one ormore UEs 115. The IAB donor may facilitate connection between corenetwork 130 and the AN (e.g., via a wired or wireless connection to corenetwork 130). That is, an IAB donor may refer to a RAN node with a wiredor wireless connection to core network 130. The IAB donor may include CU160 and at least one DU 165 (e.g., and RU 170), in which case CU 160 maycommunicate with core network 130 over an interface (e.g., a backhaullink). IAB donor and IAB nodes 104 may communicate over an Fl interfaceaccording to a protocol that defines signaling messages (e.g., an Fl APprotocol). Additionally, or alternatively, CU 160 may communicate withthe core network over an interface, which may be an example of a portionof backhaul link, and may communicate with other CUs 160 (e.g., CU 160associated with an alternative IAB donor) over an Xn-C interface, whichmay be an example of a portion of a backhaul link.

IAB node 104 may refer to a RAN node that provides IAB functionality(e.g., access for UEs 115, wireless self-backhauling capabilities). DU165 may act as a distributed scheduling node towards child nodesassociated with IAB node 104, and the IAB -MT may act as a schedulednode towards parent nodes associated with IAB node 104. That is, an IABdonor may be referred to as a parent node in communication with one ormore child nodes (e.g., an IAB donor may relay transmissions for UEsthrough one or more other IAB nodes 104). Additionally, oralternatively, IAB node 104 may also be referred to as a parent node ora child node to other IAB nodes 104, depending on the relay chain orconfiguration of the AN. Therefore, the IAB -MT entity of IAB nodes 104may provide a Uu-interface for a child IAB node 104 to receive signalingfrom parent IAB node 104, and the DU interface (e.g., DUs 165) mayprovide a Uu-interface for parent IAB node 104 to signal to child IABnode 104 or UE 115.

For example, IAB node 104 may be referred to as a parent node thatsupports communications for a child IAB node, and referred to as a childIAB node associated with an IAB donor. The IAB donor may include CU 160with a wired or wireless connection (e.g., backhaul communication link120) to core network 130 and may act as parent node to IAB nodes 104.For example, DU 165 of IAB donor may relay transmissions to UEs 115through IAB nodes 104, and may directly signal transmissions to UE 115.CU 160 of IAB donor may signal communication link establishment via anFl interface to IAB nodes 104, and IAB nodes 104 may scheduletransmissions (e.g., transmissions to UEs 115 relayed from the IABdonor) through DUs 165. That is, data may be relayed to and from IABnodes 104 via signaling over an NR Uu-interface to MT of IAB node 104.Communications with IAB node 104 may be scheduled by DU 165 of IAB donorand communications with IAB node 104 may be scheduled by DU 165 of IABnode 104.

In the case of the techniques described herein applied in the context ofa disaggregated RAN architecture, one or more components of thedisaggregated RAN architecture may be configured to support schedulingrequests for spatial multiplexing as described herein. For example, someoperations described as being performed by UE 115 or network entity 105(e.g., base station 140) may additionally, or alternatively, beperformed by one or more components of the disaggregated RANarchitecture (e.g., IAB nodes 104, DUs 165, CUs 160, RUs 170, RIC 175,SMO 180).

UE 115 may include or may be referred to as a mobile device, a wirelessdevice, a remote device, a handheld device, or a subscriber device, orsome other suitable terminology, where the “device” may also be referredto as a unit, a station, a terminal, or a client, among other examples.UE 115 may also include or may be referred to as a personal electronicdevice such as a cellular phone, a personal digital assistant (PDA), atablet computer, a laptop computer, or a personal computer. In someexamples, UE 115 may include or be referred to as a wireless local loop(WLL) station, an Internet of Things (IoT) device, an Internet ofEverything (IoE) device, or a machine type communications (MTC) device,among other examples, which may be implemented in various objects suchas appliances, or vehicles, meters, a satellite radio, a globalpositioning system (GPS) device, a global navigation satellite system(GNSS) device, a logistics controller, an unmanned aerial vehicle (UAV),a drone, a smart energy or security device, a solar panel or solararray, etc. among other examples.

UEs 115 described herein may be able to communicate with various typesof devices, such as other UEs 115 that may sometimes act as relays aswell as network entities 105 and the network equipment including macroeNBs or gNBs, small cell eNBs or gNB s, or relay base stations, amongother examples, as shown in FIG. 1 .

UEs 115 and network entities 105 may wireles sly communicate with oneanother via one or more communication links 125 (e.g., an access link)over one or more carriers. The term “carrier” may refer to a set of RFspectrum resources having a defined physical layer structure forsupporting communication links 125. For example, a carrier used forcommunication link 125 may include a portion of a RF spectrum band(e.g., a bandwidth part (BWP)) that is operated according to one or morephysical layer channels for a given radio access technology (e.g., LTE,LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisitionsignaling (e.g., synchronization signals, system information), controlsignaling that coordinates operation for the carrier, user data, orother signaling. Wireless communications system 100 may supportcommunication with UE 115 using carrier aggregation or multi-carrieroperation. UE 115 may be configured with multiple downlink componentcarriers and one or more uplink component carriers according to acarrier aggregation configuration. Carrier aggregation may be used withboth frequency division duplexing (FDD) and time division duplexing(TDD) component carriers. Communication between network entity 105 andother devices may refer to communication between the devices and anyportion (e.g., entity, sub-entity) of network entity 105. For example,the terms “transmitting,” “receiving,” or “communicating,” whenreferring to network entity 105, may refer to any portion of networkentity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RANcommunicating with another device (e.g., directly or via one or moreother network entities 105).

Signal waveforms transmitted over a carrier may be made up of multiplesubcarriers (e.g., using multi-carrier modulation (MCM) techniques suchas orthogonal frequency division multiplexing (OFDM) or discrete Fouriertransform spread OFDM (DFT-S-OFDM)). In a system employing MCMtechniques, a resource element may refer to resources of one symbolperiod (e.g., a duration of one modulation symbol) and one subcarrier,in which case the symbol period and subcarrier spacing may be inverselyrelated. The quantity of bits carried by each resource element maydepend on the modulation scheme (e.g., the order of the modulationscheme, the coding rate of the modulation scheme, or both) such that themore resource elements that a device receives and the higher the orderof the modulation scheme, the higher the data rate may be for thedevice. A wireless communications resource may refer to a combination ofan RF spectrum resource, a time resource, and a spatial resource (e.g.,a spatial layer, a beam), and the use of multiple spatial resources mayincrease the data rate or data integrity for communications with UE 115.

One or more numerologies for a carrier may be supported, where anumerology may include a subcarrier spacing (Δf) and a cyclic prefix. Acarrier may be divided into one or more BWPs having the same ordifferent numerologies. In some examples, UE 115 may be configured withmultiple BWPs. In some examples, a single BWP for a carrier may beactive at a given time and communications for UE 115 may be restrictedto one or more active BWPs.

The time intervals for network entities 105 or UEs 115 may be expressedin multiples of a basic time unit which may, for example, refer to asampling period of T_(S)=1/ (Δf_(max)·N_(f)) seconds, where Δf_(max) mayrepresent the maximum supported subcarrier spacing, and N_(f) mayrepresent the maximum supported discrete Fourier transform (DFT) size.Time intervals of a communications resource may be organized accordingto radio frames each having a specified duration (e.g., 10 milliseconds(ms)). Each radio frame may be identified by a system frame number (SFN)(e.g., ranging from 0 to 1023).

Each frame may include multiple consecutively numbered subframes orslots, and each subframe or slot may have the same duration. In someexamples, a frame may be divided (e.g., in the time domain) intosubframes, and each subframe may be further divided into a quantity ofslots. Alternatively, each frame may include a variable quantity ofslots, and the quantity of slots may depend on subcarrier spacing. Eachslot may include a quantity of symbol periods (e.g., depending on thelength of the cyclic prefix prepended to each symbol period). In somewireless communications systems 100, a slot may further be divided intomultiple mini-slots containing one or more symbols. Excluding the cyclicprefix, each symbol period may contain one or more (e.g., N_(f))sampling periods. The duration of a symbol period may depend on thesubcarrier spacing or frequency band of operation.

A subframe, a slot, a mini-slot, or a symbol may be the smallestscheduling unit (e.g., in the time domain) of the wirelesscommunications system 100 and may be referred to as a transmission timeinterval (TTI). In some examples, the TTI duration (e.g., a quantity ofsymbol periods in a TTI) may be variable. Additionally, oralternatively, the smallest scheduling unit of the wirelesscommunications system 100 may be dynamically selected (e.g., in burstsof shortened TTIs (sTTIs)).

Physical channels may be multiplexed on a carrier according to varioustechniques. A physical control channel and a physical data channel maybe multiplexed on a downlink carrier, for example, using one or more oftime division multiplexing (TDM) techniques, frequency divisionmultiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A controlregion (e.g., a control resource set (CORESET)) for a physical controlchannel may be defined by a set of symbol periods and may extend acrossthe system bandwidth or a subset of the system bandwidth of the carrier.One or more control regions (e.g., CORESETs) may be configured for a setof UEs 115. For example, one or more of UEs 115 may monitor or searchcontrol regions for control information according to one or more searchspace sets, and each search space set may include one or multiplecontrol channel candidates in one or more aggregation levels arranged ina cascaded manner. An aggregation level for a control channel candidatemay refer to an amount of control channel resources (e.g., controlchannel elements (CCEs)) associated with encoded information for acontrol information format having a given payload size. Search spacesets may include common search space sets configured for sending controlinformation to multiple UEs 115 and UE-specific search space sets forsending control information to a specific one of UEs 115.

In some examples, network entity 105 (e.g., base station 140, RU 170)may be movable and therefore provide communication coverage for a movingone of coverage areas 110. In some examples, a different one of coverageareas 110 associated with different technologies may overlap, but thedifferent one of coverage areas 110 may be supported by the same one ofnetwork entities 105. In some other examples, the overlapping coverageareas 110 associated with different technologies may be supported bydifferent ones of network entities 105. Wireless communications system100 may include, for example, a heterogeneous network in which differenttypes of network entities 105 provide coverage for various coverageareas 110 using the same or different radio access technologies.

Some of UEs 115, such as MTC or IoT devices, may be low cost or lowcomplexity devices and may provide for automated communication betweenmachines (e.g., via Machine-to-Machine (M2M) communication). M2Mcommunication or MTC may refer to data communication technologies thatallow devices to communicate with one another or network entity 105(e.g., base station 140) without human intervention. In some examples,M2M communication or MTC may include communications from devices thatintegrate sensors or meters to measure or capture information and relaysuch information to a central server or application program that makesuse of the information or presents the information to humans interactingwith the application program. Some of UEs 115 may be designed to collectinformation or enable automated behavior of machines or other devices.Examples of applications for MTC devices include smart metering,inventory monitoring, water level monitoring, equipment monitoring,healthcare monitoring, wildlife monitoring, weather and geological eventmonitoring, fleet management and tracking, remote security sensing,physical access control, and transaction-based business charging.

Some of UEs 115 may be configured to employ operating modes that reducepower consumption, such as half-duplex communications (e.g., a mode thatsupports one-way communication via transmission or reception, but nottransmission and reception concurrently). In some examples, half-duplexcommunications may be performed at a reduced peak rate. Other powerconservation techniques for UEs 115 include entering a power saving deepsleep mode when not engaging in active communications, operating over alimited bandwidth (e.g., according to narrowband communications), or acombination of these techniques. For example, some of UEs 115 may beconfigured for operation using a narrowband protocol type that isassociated with a defined portion or range (e.g., set of subcarriers orresource blocks (RBs)) within a carrier, within a guard-band of acarrier, or outside of a carrier.

Wireless communications system 100 may be configured to supportultra-reliable communications or low-latency communications, or variouscombinations thereof. For example, wireless communications system 100may be configured to support ultra-reliable low-latency communications(URLLC). UEs 115 may be designed to support ultra-reliable, low-latency,or critical functions. Ultra-reliable communications may include privatecommunication or group communication and may be supported by one or moreservices such as push-to-talk, video, or data. Support forultra-reliable, low-latency functions may include prioritization ofservices, and such services may be used for public safety or generalcommercial applications. The terms ultra-reliable, low-latency, andultra-reliable low-latency may be used interchangeably herein.

In some examples, UE 115 may be able to communicate directly with otherUEs 115 over a device-to-device (D2D) communication link 135 (e.g., inaccordance with a peer-to-peer (P2P), D2D, or sidelink protocol). Insome examples, one or more UEs 115 of a group that are performing D2Dcommunications may be within coverage area 110 of network entity 105(e.g., base station 140, RU 170), which may support aspects of such D2Dcommunications being configured by or scheduled by network entity 105.In some examples, one or more UEs 115 in such a group may be outsidecoverage area 110 of network entity 105 or may be otherwise unable to ornot configured to receive transmissions from network entity 105. In someexamples, groups of UEs 115 communicating via D2D communications maysupport a one-to-many (1:M) system in which each UE 115 transmits toeach of the other ones of UEs 115 in the group. In some examples,network entity 105 may facilitate the scheduling of resources for D2Dcommunications. In some other examples, D2D communications may becarried out between UEs 115 without the involvement of network entity105.

In some systems, D2D communication link 135 may be an example of acommunication channel, such as a sidelink communication channel, betweenvehicles (e.g., UEs 115). In some examples, vehicles may communicateusing vehicle-to-everything (V2X) communications, vehicle-to-vehicle(V2V) communications, or some combination of these. A vehicle may signalinformation related to traffic conditions, signal scheduling, weather,safety, emergencies, or any other information relevant to a V2X system.In some examples, vehicles in a V2X system may communicate with roadsideinfrastructure, such as roadside units, or with the network via one ormore network nodes (e.g., network entities 105, base stations 140, RUs170) using vehicle-to-network (V2N) communications, or with both.

Core network 130 may provide user authentication, access authorization,tracking, Internet Protocol (IP) connectivity, and other access,routing, or mobility functions. Core network 130 may be an evolvedpacket core (EPC) or 5G core (5GC), which may include at least onecontrol plane entity that manages access and mobility (e.g., a mobilitymanagement entity (MME), an access and mobility management function(AMF)) and at least one user plane entity that routes packets orinterconnects to external networks (e.g., a serving gateway (S-GW), aPacket Data Network (PDN) gateway (P-GW), or a user plane function(UPF)). The control plane entity may manage non-access stratum (NAS)functions such as mobility, authentication, and bearer management forUEs 115 served by network entities 105 (e.g., base stations 140)associated with core network 130. User IP packets may be transferredthrough the user plane entity, which may provide IP address allocationas well as other functions. The user plane entity may be connected to IPservices 150 for one or more network operators. IP services 150 mayinclude access to the Internet, Intranet(s), an IP Multimedia Subsystem(IMS), or a Packet-Switched Streaming Service.

Wireless communications system 100 may operate using one or morefrequency bands, which may be in the range of 300 megahertz (MHz) to 300gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known asthe ultra-high frequency (UHF) region or decimeter band because thewavelengths range from approximately one decimeter to one meter inlength. The UHF waves may be blocked or redirected by buildings andenvironmental features, which may be referred to as clusters, but thewaves may penetrate structures sufficiently for a macro cell to provideservice to UEs 115 located indoors. The transmission of UHF waves may beassociated with smaller antennas and shorter ranges (e.g., less than 100kilometers) compared to transmission using the smaller frequencies andlonger waves of the high frequency (HF) or very high frequency (VHF)portion of the spectrum below 300 MHz.

Wireless communications system 100 may also operate in a super highfrequency (SHF) region using frequency bands from 3 GHz to 30 GHz, alsoknown as the centimeter band, or in an extremely high frequency (EHF)region of the spectrum (e.g., from 30 GHz to 300 GHz), also known as themillimeter band. In some examples, the wireless communications system100 may support millimeter wave (mmW) communications between UEs 115 andnetwork entities 105 (e.g., base stations 140, RUs 170), and EHFantennas of the respective devices may be smaller and more closelyspaced than UHF antennas. In some examples, this may facilitate use ofantenna arrays within a device. The propagation of EHF transmissions,however, may be subject to even greater atmospheric attenuation andshorter range than SHF or UHF transmissions. The techniques disclosedherein may be employed across transmissions that use one or moredifferent frequency regions, and designated use of bands across thesefrequency regions may differ by country or regulating body.

Wireless communications system 100 may utilize both licensed andunlicensed RF spectrum bands. For example, wireless communicationssystem 100 may employ License Assisted Access (LAA), LTE-Unlicensed(LTE-U) radio access technology, or NR technology in an unlicensed bandsuch as the 5 GHz industrial, scientific, and medical (ISM) band. Whileoperating in unlicensed RF spectrum bands, devices such as networkentities 105 and UEs 115 may employ carrier sensing for collisiondetection and avoidance. In some examples, operations in unlicensedbands may be based on a carrier aggregation configuration in conjunctionwith component carriers operating in a licensed band (e.g., LAA).Operations in unlicensed spectrum may include downlink transmissions,uplink transmissions, P2P transmissions, or D2D transmissions, amongother examples.

Network entity 105 (e.g., base station 140, RU 170) or UE 115 may beequipped with multiple antennas, which may be used to employ techniquessuch as transmit diversity, receive diversity, multiple-inputmultiple-output (MIMO) communications, or beamforming. The antennas ofnetwork entity 105 or UE 115 may be located within one or more antennaarrays or antenna panels, which may support MIMO operations or transmitor receive beamforming. For example, one or more base station antennasor antenna arrays may be co-located at an antenna assembly, such as anantenna tower. In some examples, antennas or antenna arrays associatedwith network entity 105 may be located in diverse geographic locations.Network entity 105 may have an antenna array with a set of rows andcolumns of antenna ports that network entity 105 may use to supportbeamforming of communications with UE 115. Likewise, UE 115 may have oneor more antenna arrays that may support various MIMO or beamformingoperations. Additionally, or alternatively, an antenna panel may supportRF beamforming for a signal transmitted via an antenna port.

Network entities 105 or UEs 115 may use MIMO communications to exploitmultipath signal propagation and increase the spectral efficiency bytransmitting or receiving multiple signals via different spatial layers.Such techniques may be referred to as spatial multiplexing. The multiplesignals may, for example, be transmitted by the transmitting device viadifferent antennas or different combinations of antennas. Likewise, themultiple signals may be received by the receiving device via differentantennas or different combinations of antennas. Each of the multiplesignals may be referred to as a separate spatial stream and may carryinformation associated with the same data stream (e.g., the samecodeword) or different data streams (e.g., different codewords).Different spatial layers may be associated with different antenna portsused for channel measurement and reporting. MIMO techniques includesingle-user MIMO (SU-MIMO), where multiple spatial layers aretransmitted to the same receiving device, and multiple-user MIMO(MU-MIMO), where multiple spatial layers are transmitted to multipledevices.

Beamforming, which may also be referred to as spatial filtering,directional transmission, or directional reception, is a signalprocessing technique that may be used at a transmitting device or areceiving device (e.g., network entity 105, UE 115) to shape or steer anantenna beam (e.g., a transmit beam, a receive beam) along a spatialpath between the transmitting device and the receiving device.Beamforming may be achieved by combining the signals communicated viaantenna elements of an antenna array such that some signals propagatingat particular orientations with respect to an antenna array experienceconstructive interference while others experience destructiveinterference. The adjustment of signals communicated via the antennaelements may include a transmitting device or a receiving deviceapplying amplitude offsets, phase offsets, or both to signals carriedvia the antenna elements associated with the device. The adjustmentsassociated with each of the antenna elements may be defined by abeamforming weight set associated with a particular orientation (e.g.,with respect to the antenna array of the transmitting device orreceiving device, or with respect to some other orientation).

Network entity 105 or UE 115 may use beam sweeping techniques as part ofbeamforming operations. For example, network entity 105 (e.g., basestation 140, RU 170) may use multiple antennas or antenna arrays (e.g.,antenna panels) to conduct beamforming operations for directionalcommunications with UE 115. Some signals (e.g., synchronization signals,reference signals, beam selection signals, or other control signals) maybe transmitted by network entity 105 multiple times along differentdirections. For example, network entity 105 may transmit a signalaccording to different beamforming weight sets associated with differentdirections of transmission. Transmissions along different beamdirections may be used to identify (e.g., by a transmitting device, suchas network entity 105, or by a receiving device, such as UE 115) a beamdirection for later transmission or reception by network entity 105.

Some signals, such as data signals associated with a particularreceiving device, may be transmitted by a transmitting device (e.g.,transmitting network entity 105, transmitting UE 115) along a singlebeam direction (e.g., a direction associated with the receiving device,such as receiving network entity 105 or receiving UE 115). In someexamples, the beam direction associated with transmissions along asingle beam direction may be determined based on a signal that wastransmitted along one or more beam directions. For example, UE 115 mayreceive one or more of the signals transmitted by network entity 105along different directions and may report to network entity 105 anindication of the signal that UE 115 received with a highest signalquality or an otherwise acceptable signal quality.

In some examples, transmissions by a device (e.g., by network entity 105or UE 115) may be performed using multiple beam directions, and thedevice may use a combination of digital precoding or beamforming togenerate a combined beam for transmission (e.g., from network entity 105to UE 115). The UE 115 may report feedback that indicates precodingweights for one or more beam directions, and the feedback may correspondto a configured set of beams across a system bandwidth or one or moresub-bands. Network entity 105 may transmit a reference signal (e.g., acell-specific reference signal (CRS), a channel state informationreference signal (CSI-RS)), which may be precoded or unprecoded. UE 115may provide feedback for beam selection, which may be a precoding matrixindicator (PMI) or codebook-based feedback (e.g., a multi-panel typecodebook, a linear combination type codebook, a port selection typecodebook). Although these techniques are described with reference tosignals transmitted along one or more directions by network entity 105(e.g., base station 140, RU 170), UE 115 may employ similar techniquesfor transmitting signals multiple times along different directions(e.g., for identifying a beam direction for subsequent transmission orreception by UE 115) or for transmitting a signal along a singledirection (e.g., for transmitting data to a receiving device).

A receiving device (e.g., UE 115) may perform reception operations inaccordance with multiple receive configurations (e.g., directionallistening) when receiving various signals from a receiving device (e.g.,network entity 105), such as synchronization signals, reference signals,beam selection signals, or other control signals. For example, areceiving device may perform reception in accordance with multiplereceive directions by receiving via different antenna subarrays, byprocessing received signals according to different antenna subarrays, byreceiving according to different receive beamforming weight sets (e.g.,different directional listening weight sets) applied to signals receivedat multiple antenna elements of an antenna array, or by processingreceived signals according to different receive beamforming weight setsapplied to signals received at multiple antenna elements of an antennaarray, any of which may be referred to as “listening” according todifferent receive configurations or receive directions. In someexamples, a receiving device may use a single receive configuration toreceive along a single beam direction (e.g., when receiving a datasignal). The single receive configuration may be aligned along a beamdirection determined based on listening according to different receiveconfiguration directions (e.g., a beam direction determined to have ahighest signal strength, highest signal-to-noise ratio (SNR), orotherwise acceptable signal quality based on listening according tomultiple beam directions).

Wireless communications system 100 may be a packet-based network thatoperates according to a layered protocol stack. In the user plane,communications at the bearer or PDCP layer may be IP-based. An RLC layermay perform packet segmentation and reassembly to communicate overlogical channels. A MAC layer may perform priority handling andmultiplexing of logical channels into transport channels. The MAC layermay also use error detection techniques, error correction techniques, orboth to support retransmissions at the MAC layer to improve linkefficiency. In the control plane, the RRC protocol layer may provideestablishment, configuration, and maintenance of an RRC connectionbetween UE 115 and network entity 105 or core network 130 supportingradio bearers for user plane data. At the PHY layer, transport channelsmay be mapped to physical channels.

UEs 115 and network entities 105 may support retransmissions of data toincrease the likelihood that data is received successfully. Hybridautomatic repeat request (HARQ) feedback is one technique for increasingthe likelihood that data is received correctly over a communication link(e.g., communication link 125, D2D communication link 135). HARQ mayinclude a combination of error detection (e.g., using a cyclicredundancy check (CRC)), forward error correction (FEC), andretransmission (e.g., automatic repeat request (ARQ)). HARQ may improvethroughput at the MAC layer in poor radio conditions (e.g., lowsignal-to-noise conditions). In some examples, a device may supportsame-slot HARQ feedback, where the device may provide HARQ feedback in aspecific slot for data received in a previous symbol in the slot. Insome other examples, the device may provide HARQ feedback in asubsequent slot, or according to some other time interval.

FIG. 2 is a block diagram illustrating examples of base station 140 andUE 115 according to one or more aspects. Base station 140 and UE 115 maybe any of the network entities or base stations and one of the UEs inFIG. 1 . For a restricted association scenario (as mentioned above),base station 140 and UE 115 may be operating in coverage area 110 ofbase station 140. As shown in FIG. 2 , base station 140 may be equippedwith antennas 234 a through 234 t, and UE 115 may be equipped withantennas 252 a through 252 r for facilitating wireless communications.

At base station 140, transmit processor 220 may receive data from datasource 212 and control information from controller 240, such as aprocessor. The control information may be for a physical broadcastchannel (PBCH), a physical control format indicator channel (PCFICH), aphysical hybrid-ARQ (automatic repeat request) indicator channel(PHICH), a physical downlink control channel (PDCCH), an enhancedphysical downlink control channel (EPDCCH), an MTC physical downlinkcontrol channel (MPDCCH), etc. The data may be for a physical downlinkshared channel (PDSCH), etc. Additionally, transmit processor 220 mayprocess (e.g., encode and symbol map) the data and control informationto obtain data symbols and control symbols, respectively. Transmitprocessor 220 may also generate reference symbols, e.g., for the primarysynchronization signal (PSS) and secondary synchronization signal (SSS),and cell-specific reference signal. Transmit (TX) MIMO processor 230 mayperform spatial processing (e.g., precoding) on the data symbols, thecontrol symbols, or the reference symbols, if applicable, and mayprovide output symbol streams to modulators (MODs) 232 a through 232 t.For example, spatial processing performed on the data symbols, thecontrol symbols, or the reference symbols may include precoding. Eachmodulator 232 may process a respective output symbol stream (e.g., forOFDM, etc.) to obtain an output sample stream. Each modulator 232 mayadditionally or alternatively process (e.g., convert to analog, amplify,filter, and upconvert) the output sample stream to obtain a downlinksignal. Downlink signals from modulators 232 a through 232 t may betransmitted via antennas 234 a through 234 t, respectively.

At UE 115, antennas 252 a through 252 r may receive the downlink signalsfrom base station 140 and may provide received signals to demodulators(DEMODs) 254 a through 254 r, respectively. Each demodulator 254 maycondition (e.g., filter, amplify, downconvert, and digitize) arespective received signal to obtain input samples. Each demodulator 254may further process the input samples (e.g., for OFDM, etc.) to obtainreceived symbols. MIMO detector 256 may obtain received symbols fromdemodulators 254 a through 254 r, perform MIMO detection on the receivedsymbols if applicable, and provide detected symbols. Receive processor258 may process (e.g., demodulate, deinterleave, and decode) thedetected symbols, provide decoded data for UE 115 to data sink 260, andprovide decoded control information to controller 280, such as aprocessor.

On the uplink, at UE 115, transmit processor 264 may receive and processdata (e.g., for a physical uplink shared channel (PUSCH)) from datasource 262 and control information (e.g., for a physical uplink controlchannel (PUCCH)) from controller 280. Additionally, transmit processor264 may also generate reference symbols for a reference signal. Thesymbols from transmit processor 264 may be precoded by TX MIMO processor266 if applicable, further processed by modulators 254 a through 254r(e.g., for SC-FDM, etc.), and transmitted to base station 140. At basestation 140, the uplink signals from UE 115 may be received by antennas234, processed by demodulators 232, detected by MIMO detector 236 ifapplicable, and further processed by receive processor 238 to obtaindecoded data and control information sent by UE 115. Receive processor238 may provide the decoded data to data sink 239 and the decodedcontrol information to controller 240.

Controllers 240 and 280 may direct the operation at base station 140 andUE 115, respectively. Controller 240 or other processors and modules atbase station 140 or controller 280 or other processors and modules at UE115 may perform or direct the execution of various processes for thetechniques described herein, such as to perform or direct the executionillustrated in FIGS. 3A and 3B, or other processes for the techniquesdescribed herein. Memories 242 and 282 may store data and program codesfor base station 140 and UE 115, respectively. Scheduler 244 mayschedule UEs for data transmission on the downlink or the uplink.

In some cases, UE 115 and base station 140 may operate in a shared radiofrequency spectrum band, which may include licensed or unlicensed (e.g.,contention-based) frequency spectrum. In an unlicensed frequency portionof the shared radio frequency spectrum band, UEs 115 or base stations105 may traditionally perform a medium-sensing procedure to contend foraccess to the frequency spectrum. For example, UE 115 or base station140 may perform a listen-before-talk or listen-before-transmitting (LBT)procedure such as a clear channel assessment (CCA) prior tocommunicating in order to determine whether the shared channel isavailable. In some implementations, a CCA may include an energydetection procedure to determine whether there are any other activetransmissions. For example, a device may infer that a change in areceived signal strength indicator (RSSI) of a power meter indicatesthat a channel is occupied. Specifically, signal power that isconcentrated in a certain bandwidth and exceeds a predetermined noisefloor may indicate another wireless transmitter. A CCA also may includedetection of specific sequences that indicate use of the channel. Forexample, another device may transmit a specific preamble prior totransmitting a data sequence. In some cases, an LBT procedure mayinclude a wireless node adjusting its own backoff window based on theamount of energy detected on a channel or theacknowledge/negative-acknowledge (ACK/NACK) feedback for its owntransmitted packets as a proxy for collisions.

In general, four categories of LBT procedure have been suggested forsensing a shared channel for signals that may indicate the channel isalready occupied. In a first category (CAT 1 LBT), no LBT or CCA isapplied to detect occupancy of the shared channel. A second category(CAT 2 LBT), which may also be referred to as an abbreviated LBT, asingle-shot LBT, a 16-μs, or a 25-μs LBT, provides for the node toperform a CCA to detect energy above a predetermined threshold or detecta message or preamble occupying the shared channel. The CAT 2 LBTperforms the CCA without using a random back-off operation, whichresults in its abbreviated length, relative to the next categories.

A third category (CAT 3 LBT) performs CCA to detect energy or messageson a shared channel, but also uses a random back-off and fixedcontention window. Therefore, when the node initiates the CAT 3 LBT, itperforms a first CCA to detect occupancy of the shared channel. If theshared channel is idle for the duration of the first CCA, the node mayproceed to transmit. However, if the first CCA detects a signaloccupying the shared channel, the node selects a random back-off basedon the fixed contention window size and performs an extended CCA. If theshared channel is detected to be idle during the extended CCA and therandom number has been decremented to 0, then the node may begintransmission on the shared channel. Otherwise, the node decrements therandom number and performs another extended CCA. The node would continueperforming extended CCA until the random number reaches 0. If the randomnumber reaches 0 without any of the extended CCAs detecting channeloccupancy, the node may then transmit on the shared channel. If at anyof the extended CCA, the node detects channel occupancy, the node mayre-select a new random back-off based on the fixed contention windowsize to begin the countdown again.

A fourth category (CAT 4 LBT), which may also be referred to as a fullLBT procedure, performs the CCA with energy or message detection using arandom back-off and variable contention window size. The sequence of CCAdetection proceeds similarly to the process of the CAT 3 LBT, exceptthat the contention window size is variable for the CAT 4 LBT procedure.

Sensing for shared channel access may also be categorized into eitherfull-blown or abbreviated types of LBT procedures. For example, a fullLBT procedure, such as a CAT 3 or CAT 4 LBT procedure, includingextended channel clearance assessment (ECCA) over a non-trivial numberof 9-μs slots, may also be referred to as a “Type 1 LBT.” An abbreviatedLBT procedure, such as a CAT 2 LBT procedure, which may include aone-shot CCA for 16-μs or 25-μs, may also be referred to as a “Type 2LBT.”

Use of a medium-sensing procedure to contend for access to an unlicensedshared spectrum may result in communication inefficiencies. This may beparticularly evident when multiple network operating entities (e.g.,network operators) are attempting to access a shared resource. Inwireless communications system 100, base stations 105 and UEs 115 may beoperated by the same or different network operating entities. In someexamples, an individual base station 140 or UE 115 may be operated bymore than one network operating entity. In other examples, each basestation 140 and UE 115 may be operated by a single network operatingentity. Requiring each base station 140 and UE 115 of different networkoperating entities to contend for shared resources may result inincreased signaling overhead and communication latency.

In some cases, operations in unlicensed bands may be based on a carrieraggregation configuration in conjunction with component carriersoperating in a licensed band (e.g., LAA). Operations in unlicensedspectrum may include downlink transmissions, uplink transmissions,peer-to-peer transmissions, or a combination of these. Duplexing inunlicensed spectrum may be based on frequency division duplexing (FDD),time division duplexing (TDD), or a combination of both.

As wireless technologies advance, considerations for the next generationradio access technology designs may take into account experiences andissues experienced in prior or current designs in order to determineimproved approaches in such next generations technologies. Nextgeneration research and development has been ongoing as part of theNorth American Next G Alliance (NGA) and its research topics for thenext generation or sixth generation (6G) designs. One topic ofconsideration in such 6G technologies relate to a redesign of millimeterwave (mmW) communication technologies.

Such 6G research includes redesigning mmW technologies to overcomesignificant challenges experienced in mmW bands that occurs in 5Goperations. Research for redesigning such mmW technologies includeconsiderations for overcoming significant path loss in mmW bands;overcoming blockage from hand, body, walls, foliage, etc.; optimizingmmWave designs for the smartphone form factor; satisfying maximumpermissible exposure requirements; handling of beam pairing, trackingand recovery; densifying networks in a cost-effective way; and improvingpower efficiency on networks and devices.

Several areas of research for addressing a redesign of such mmWtechnologies include but are not limited to research of low latency andoverhead beam management; autonomous beam management; seamless mobilityacross nodes (e.g., gNBs, relays and (smart) repeaters); topologicalenhancements for densifying network; power efficient radio frequency(RF) frontend designs and beamforming; waveform and modulation forbetter power efficiency; designing reuse across different bands, e.g.,including sub-THz; uplink coverage enhancements; power savings fornetwork entities and UEs; power efficient physical (PHY) layeroperations and procedure; sidelink operational enhancements; and thelike.

The layer 1 (L1) measurement report may be used by a UE to report theindex and associated measurement for the best beam(s) to use forcommunications with the UE. The measurements are performed for variouscontrol signals, such as non-zero power (NZP) channel stateinformation—reference signals (CSI-RS), synchronization signal blocks(SSB, or CSI—interference measurement (CSI-IM). The measurements can beeither L1 reference signal receive power (L1-RSRP) or L1signal-to-interference plus noise ratio (L1-SINR), or the like.Measurement configuration signals are received at the UE whichconfigures the UE measurement process, including configuration ofmeasurement resources, the type of reporting, and report settings.

The UE may generally receive an RRC message that includes resourceconfiguration that configures one or more CSI resource sets (e.g., NZPCSI-RS, SSB, or CSI-IM) and a type of reporting (e.g., periodic,semi-persistent, or aperiodic). The RRC message may further include oneor more CSI reporting settings, which indicate the measured quantitiesto report, between the CSI-related, L1-RSRP-related, or L1-SINR-relatedquantities. CSI report settings are linked to CSI resource settings. Forexample, when the report configuration is periodic, the resourceconfiguration (e.g., the CSI resource sets) may also be period with thereport transmitted on PUSCH. When the report configuration issemi-persistent, the resource configuration may be either periodic orsemi-persistent with the report transmitted either on PUCCH, whileactivated/deactivated using a medium access control—control element(MAC-CE), or on PUSCH, while the report transmission is triggered usinga downlink control information (DCI) message. And, when the reportconfiguration is aperiodic, the resource configuration can be any ofperiodic, semi-persistent, or aperiodic with the report transmitted onPUCCH.

Aperiodic and semi-persistent reporting may have one or two lists oftrigger states for triggering the aperiodic and semi-persistent reports.Each such trigger state for aperiodic reporting may contain a list ofassociated CSI report configurations indicating the resource setidentifiers (IDs) for channel measurement resources (CMRs) andoptionally for interference measurement resources (IMRs). Each triggerstate for semi-persistent reporting may contain one associated CSIreport configuration. For aperiodic and semi-persistent statetriggering, the UE is configured via the RRC signaling of the resourceand report configuration, while the reporting is triggered either by aDCI message, which selects the report configuration from the list fortransmitting the L1 measurement report on PUSCH for aperiodic andsemi-persistent type reporting, or by a MAC-CE for semi-persistentreporting transmitted on PUCCH.

When the UE is configured to report L1-RSRP measurements, the resourcesetting associated with L1-RSRP may be configured with up to 16 CSI-RSresource sets with up to 64 resources within each set for a maximumtotal of 128 CSI-RS resources. When the UE is configured to reportL1-SINR measurements, the resource setting associated with L1-SINR maybe configured with up to 64 CSI-RS resources or up to 64 SSBs. Table 1below identifies multiple combinations of CMRs and IMRs that may beprovided for the L1-SINR measurements.

TABLE 1 L1-SINR Combinations Combination CMR IMR Comb. 1 NZP CSI-RS(Same) NZP CSI-RS Comb. 2 SSB ZP CSI-RS Comb. 3 SSB NZP CSI-RS Comb. 4NZP CSI-RS ZP CSI-RS Comb. 5 NZP CSI-RS (Dif) NZP CSI-RS

Some UEs may simultaneously receiving multiple beams, such as when a UEis capable of receiving on multiple antenna panels or can receivemultiple reflected transmit beam using the same antenna panel. In suchscenarios, the UEs may provide group-based beam reports. The group-basedbeam report enables a network entity to transmit data in two beams, orto switch transmit beams without delay, within the beam group.

Group-based beam reporting may be enabled or disabled, which will affectthe report structure of the UE. When group-based beam reporting isdisabled, the UE may report multiple different CSI-RS resourceindicators (CRIs) or synchronization signal (SS)/physical block channel(PBCH) resource block indicator (SSBRI), based on the particularconfiguration, for each report setting. When group-based beam reportingis enabled, the UE may report two different CRI or SSBRI for each reportsetting. The largest measured value may be quantized to 7-bits, whilethe other measurements reflect a differential with respect to largestmeasurement and may be quantized to 4-bits.

The UE transmits the L1 measurement report on a certain receive beam forthe network entity. For periodic and semi-persistent L1 measurementreports, the network entity will periodically tune its antenna panel tothe direction from which the UE is configured to send the report at thattime. This causes beam direction reservation, where the beam directionis reserved by the network entity for that UE during the periodicreporting times. This can cause delays to other high priority UEs indifferent directions, as they will wait until their beam directionbecomes available. The delay can be significant for very delay-sensitiveapplications/usages.

For the payload of an L1 measurement report, depending on the number ofRS s in the report and the number of settings, the L1 report payload maybe relatively large and can cause unnecessary overhead when no newinformation is sent. If more or fewer beams are to be reported due toenvironment changes, the UE would still send the smaller or largerreport, which is not optimized. The various aspects of the presentdisclosure that support adaptable configuration for periodic andsemi-persistent L1 measurement reporting are intended to address thelimitations with the current procedures.

FIGS. 3A and 3B are flow diagrams illustrating example processes 30 and31 that support adaptable configuration for periodic and semi-persistentL1 measurement reporting according to one or more aspects. Operations ofprocess 30 may be performed by a UE, such as UE 115 described above withreference to FIGS. 1 and 2 , or a UE described with reference to FIG. 8. For example, example operations (also referred to as “blocks”) ofprocess 30 may enable UE 115 to support adaptable configuration forperiodic and semi-persistent L1 measurement reporting. Operations ofprocess 31 may be performed by a network entity, such as network entity105 described above with reference to FIGS. 1 and 2 , or network entity105 described with reference to FIG. 9 . For example, example operations(also referred to as “blocks”) of process 31 may enable network entity105 to support adaptable configuration for periodic and semi-persistentL1 measurement reporting.

Process 30 may be described with respect to FIG. 8 . FIG. 8 is a blockdiagram of an example UE 115 that supports adaptable configuration forperiodic and semi-persistent L1 measurement reporting according tovarious aspects of the present disclosure. UE 115 may be configured toperform operations, including the blocks of a process described withreference to FIG. 3 . In some implementations, UE 115 includes thestructure, hardware, and components shown and described with referenceto UE 115 of FIGS. 1-2 . For example, UE 115 includes controller 280,which operates to execute logic or computer instructions stored inmemory 282, as well as controlling the components of UE 115 that providethe features and functionality of UE 115. UE 115, under control ofcontroller 280, transmits and receives signals via wireless radios 800a-r and antennas 252 a-r. Wireless radios 800 a-r include variouscomponents and hardware, as illustrated in FIG. 2 for UE 115, includingmodulator and demodulators 254 a-r, MIMO detector 256, receive processor258, transmit processor 264, and TX MIMO processor 266.

As shown, memory 282 may include L1 measurement report configuration801, report modification logic 802, measurement logic 803, and L1measurement report generator 804. L1 measurement report configuration801 includes the configuration information that configures the one ormore original reporting occasions in addition to the configuration ofthe measurement reporting (e.g., number of CRIs to report, number ofreport settings, resource settings, type of reporting, etc.). Reportmodification logic 802 may be configured to enable functionality withinUE 115 for identifying a dynamic modification indication with themodification to be applied to any of the configured reporting occasions.Measurement logic 803 may be configured to provide functionality to UE115 for measuring (e.g., L1-RSRP, L1-SINR, etc.) the appropriatereference signals configured in the CSI resource settings to indicatethe best beams for communication with UE 115. L1 measurement reportgenerator 804 may be configured to use the resulting measurements frommeasurement logic 803 to generate the L1 measurement logic forgroup-based beam reporting, when group-based beam reporting is enabled,or non-group-based beam reporting, when group-based beam reporting isnot enabled. UE 115 may receive signals from or transmit signals to oneor more network entities, such as network entity 105 of FIGS. 1-2 and 9.

Process 31 may be described with respect to FIG. 9 . FIG. 9 is a blockdiagram of an example network entity 105 that supports adaptableconfiguration for periodic and semi-persistent L1 measurement reportingaccording to various aspects of the present disclosure. Network entitymay be configured to perform operations, including the blocks of aprocess described with reference to FIG. 3 . In some implementations,network entity 105 includes the structure, hardware, and componentsshown and described with reference to base station 140 of FIGS. 1-2 .For example, network 105 may include controller 240, which operates toexecute logic or computer instructions stored in memory 242, as well ascontrolling the components of network entity 105 that provide thefeatures and functionality of network entity 105. Network entity 105,under control of controller 240, transmits and receives signals viawireless radios 900 a-t and antennas 234 a-t. Wireless radios 900 a-tinclude various components and hardware, as illustrated in FIG. 2 forbase station 140, including modulator and demodulators 232 a-t, transmitprocessor 220, TX MIMO processor 230, MIMO detector 236, and receiveprocessor 238.

As shown, memory 242 may include report configuration logic 901, L1measurement report configuration 902, and report modification logic 903.Report configuration logic 901 may be configured to enable functionalitywithin network entity 105 L1 measurement report configuration 902includes the configuration information that configures the one or moreoriginal reporting occasions in addition to the configuration of themeasurement reporting. Report modification logic 903 may be configuredto enable functionality within network entity 105 for identifying adynamic modification indication with the modification to be applied toany of the configured reporting occasions. Network entity 105 mayreceive signals from or transmit signals to one or more UEs, such as UE115 of FIGS. 1-2 and 8 .

The details of processes 30 and 31, illustrated in FIGS. 3A and 3B, willbe described below in a sequential manner of actions or communicationsthat occur between a network entity implementing process 31 and a UEimplementing process 30.

At block 310, a network entity transmits an L1 measurement reportconfiguration via RRC signaling, wherein the L1 measurement reportconfiguration includes configuration of one or more report occasions forL1 measurement report transmission from one or more UEs. A networkentity, such as network entity 105, may execute, under control ofcontroller 240, report configuration logic 901, stored in memory 242.The execution of the instructions and code of report configuration logic(referred to herein as “the execution environment”) enablesimplementation of functionality within network entity 105 for settingthe details of the configuration for L1 measurement reporting by aserved UE. Within the execution environment of report configurationlogic 901, network entity 105 sets the L1 measurement reportconfiguration for the served UE, which is then stored in memory at L1measurement report configuration 902. The report configuration mayinclude number of CRIs to report, number of report settings, resourcesettings, type of reporting, and the like, as well as defining the oneor more reporting occasions, whether for periodic or semi-persistentreporting. Under control of controller 240, network entity 105 may thentransmit the configuration information at L1 measurement reportconfiguration 902 via RRC signaling using wireless radios 900 a-t andantennas 234 a-t.

At block 300, a UE receives the L1 measurement report configuration viaRRC signaling, wherein the L1 measurement report configuration includesconfiguration of one or more report occasions for L1 measurement reporttransmission from the UE. A UE, such as UE 115, operating in a networkthat uses L1 measurement reports, may receive the L1 measurement reportconfiguration transmitted from a serving base station via antennas 252a-r and wireless radios 800 a-r. UE 115 may extract the configurationinformation and store the information in memory 280 at L1 measurementreport configuration 801. As noted above, the report configurationinformation includes configuration of the L1 measurement reporting aswell as identifying the one or more reporting occasions, whether forperiodic or semi-persistent reporting, for UE 115 to transmit the L1measurement reports.

At blocks 301 and 311, the UE and the network entity, respectively,identify a dynamic modification indication, wherein the dynamicmodification indication identifies a modification to one or moreupcoming report occasions of the one or more report occasions. Accordingto the aspects of the present disclosure, UE 115, under control ofcontroller 280, may execute report modification logic 802, stored inmemory 282. Similarly, network entity 105, under control of controller240, may execute report modification logic 903, stored in memory 242.The execution environments of report modification logic 802 and reportmodification logic 903 enable the functionality within UE 115 andnetwork entity 105, respectively, for identifying dynamic modificationindications as well as identifying the modifications within the dynamicmodification indication. Such dynamic modification indications may beexplicit, such as with explicit modification request informationtransmitted from UE 115 or from network entity 105 to the other entity,or implicit based on predetermined rules and various communicationconditions.

At block 312, the network entity tunes an antenna panel in a beamdirection reserved for a next report occasion of the one or moreupcoming report occasions according to the modification. Once networkentity 105 identifies the dynamic modification indication along with theidentified modification, within the execution environment of reportmodification logic 903, network entity 105 may tune antennas 234 a-ttoward a particular UE to monitor for an L1 measurement report. Theparameters for network entity 105 to use in tuning antennas 234 a-tinclude the report modification applied to the originally configuredreporting occasion.

At block 302, the UE transmits an L1 measurement report in the one ormore upcoming report occasions according to the modification. Using thereport configuration in L1 measurement report configuration 801, UE 115,under control of controller 280, executes measurement logic 803, storedin memory 282. The execution environment of measurement logic 803enables the functionality of UE 115 to measure particular referencesignals, such as providing L1-RSRP or L1-SINR measurements of thereference signals identified and selected from the set of CSI resourcesconfigured for L1 measurement reporting. After calculating themeasurements of the selected reference signals, UE 115, under control ofcontroller 280, may execute L1 measurement report generator 804, storedin memory 282. The execution environment of L1 measurement reportgenerator 804 enables the functionality of UE 115 to generate an L1measurement report using the measurements calculated of the selectedreference signals. UE 115 may then transmit the L1 measurement reportvia wireless signals 800 a-r and antennas 252 a-r.

At block 313, the network entity receives the L1 measurement report inthe next report occasion report occasions. After tuning antennas 234 a-tin the direction of the served UE at the time and location defined bythe report modification being applied to the configured originalreporting occasion, network entity 105 may receive the L1 measurementreport transmitted from the served UE via antennas 234 a-t and wirelessradios 900 a-t.

As described with reference to FIGS. 3A and 3B, the present disclosureprovides techniques for adaptable configuration for periodic andsemi-persistent L1 measurement reporting. The ability of either a UE ornetwork entity to dynamically request modification of the L2 measurementreporting operations allows more flexibility in reporting andopportunity for more efficient use of communication resources. Forexample, where communication with a higher priority UE may be delayedbecause of uplink beam reservation for a periodic or semi-persistentreporting occasion, the network entity may request a modification in theconfigured reporting occasions in order to more efficiently serve thehigher-priority UE. Additionally, when no new information would be sentin a measurement report, the UE may request a modification that skips orcancels those reporting occasions in order to reduce unnecessary payloador unnecessary use of resources.

FIG. 4 is a block diagram illustrating L1 reporting operations 40between UE 115 and network entity 105 configured to support adaptableconfiguration for periodic and semi-persistent L1 measurement reportingaccording to aspects of the present disclosure. Network entity 105transmits an L1 measurement report configuration via RRC signaling 400to UE 115. The L1 measurement report configuration configures UE 115with a number of reporting occasions for either configured periodic orsemi-persistent L1 measurement reporting. The reporting occasions areconfigured to occur at an L1 report period. Either of UE 115 or networkentity 105 may identify a dynamic modification indication, which may beidentified explicitly using signaling from network entity 105 (e.g.,wake-up signals, demodulation reference signals (DMRS), downlink controlinformation (DCI) messages, MAC-CE (of either dynamic grant orsemi-persistent scheduling), piggy-backed on either dynamic grant orsemi-persistent scheduling messages), explicitly using signaling from UE115 (e.g., uplink resource modification indication (RMI), MAC-CE (eitherdynamic grant or configured grant), piggy-backed on a dynamic grant orconfigured grant messages, PUCCH, scheduling request (SR), or the like),or implicitly based on preconfigured rules.

For example, UE 115 transmits an L1 measurement report and a MAC-CE atreporting occasion 401. The MAC-CE dynamically identifies a modificationof the L1 measurement reporting to shift the next upcoming reportoccasions by a time, T₁. As illustrated, the MAC-CE transmitted from UE115 corresponds to the dynamic modification indication including themodification to be applied to original reporting occasions 402 and 404.The modification directs UE 115 to transmit L1 measurement reports atmodified reporting occasions 403 and 405. Network entity 105, uponreceiving the MAC-CE will also know to adjust when it tunes its antennapanels in the direction of UE 115 to receive the L1 measurement reportsat the modified locations, modified reporting occasions 403 and 405.

The modification communicated with the dynamic modification indicationmay be a semi-persistent modification, which is applied to all remainingconfigured original reporting occasions after identifying the dynamicmodification indication, or a discrete modification to be applied for adiscrete number of upcoming reporting occasions. The modificationdelivered with the MAC-CE in reporting occasion 401, for purposes of theillustrated example, is semi-persistent, which would cause UE 115 toapply the T₁ shift in time to original reporting occasions 402 and 404to transmit L1 measurement reports at modified reporting occasions 403and 405, respectively. UE 115 stops applying the modification identifiedin the MAC-CE after receiving a new dynamic modification indicationincluding a new modification via DCI 403 transmitted by network entity105. The new modification identifies a time shift, T₂, and frequencyshift, Δf, for UE 115 to apply to one upcoming reporting occasion,original reporting occasion 407. UE 115 may then transmit an L1measurement report at modified reporting occasion 408. Similarly,network entity 105 knows to tune its antenna panel toward the directionof UE 115 at modified reporting occasion 408 to receive the L1measurement report.

As noted above, the dynamic modification indication may also beidentified implicitly. For example, upon transmitting the L1 measurementreport at modified reporting occasion 408, UE 115 determines that thenext reporting occasion, original reporting occasion 409, is less than apredetermined minimum time, T_(m), from its transmission of the L1measurement report at modified reporting occasion 408. Based on thisdetermination, UE 115 is configured to skip the next reporting occasion,original reporting occasion 409.

It should be noted that the modification to the configured originalreporting occasions may be a shift in time (either advance in time ordelay), as indicated in the T₁ time shifts for modified reportingoccasions 403 and 405, a shift in frequency, or both time and frequency,as indicated in the T₂ time and Δf frequency shifts of modifiedreporting occasion 408. However, additional types of modifications mayfurther be applicable, such as canceling or skipping occasions,modifying the measurement reporting configuration (e.g., modification ofthe number of CRIs to report, number of CSI report settings, CSIresource settings, etc.), adding extra reporting occasions, beamchanges, and the like.

FIG. 5 is a block diagram illustrating L1 reporting operations 50between UE 115 and network entity 105 configured to support adaptableconfiguration for periodic and semi-persistent L1 measurement reportingaccording to aspects of the present disclosure. Network entity 105transmits an L1 measurement report configuration via RRC signaling 500to UE 115. The L1 measurement report configuration configures UE 115with a number of reporting occasions at an L1 report period for eitherconfigured periodic or semi-persistent L1 measurement reporting.

Either one of UE 115 or network entity 105 may identify a dynamicmodification indicator identifying a modification to the configuredoriginal reporting occasions. As illustrated in FIG. 5 , the dynamicmodification indicator includes a pattern indication 506 identifying anON/OFF pattern for transmitting (ON) or skipping/canceling (OFF)transmission of the L1 measurement reports in an associated configuredoriginal reporting occasion. For example, pattern indication 506identifies the ON/OFF pattern for five of the configured originalreporting occasions. The pattern instructs UE 115 to transmit an L1measurement report at reporting occasions 501, 503, and 505, and to skiptransmission a report at original reporting occasions 502 and 504.

Additional aspects illustrated in FIG. 5 may provide for network entity105 to configure UE 115 to implicitly add additional PDCCH monitoring orSR occasions when a modification instructs UE 115 to skip transmitting areport at a particular reporting occasion. Thus, according to theadditional aspect, network entity 105 transmits configuration message505 that configures UE 115 to add either additional PDCCH monitoringoccasions or additional SR occasions when UE 115 detects a skippedoriginal reporting occasions. This configuration message 505 may bereceived by UE 115 at some point prior to the current L1 measurementreporting occasions. Accordingly, as illustrated in FIG. 5 , uponidentifying the OFF patterns within pattern indication 506, UE 115 maydetermine, based on its configuration from configuration message 505, toadd either additional PDCCH monitoring occasions or additional SRoccasions. Thus, after UE 115 skips transmission of a report at originalreporting occasion 502, UE 115 may add an additional PDCCH monitoringoccasion or an additional SR occasion at 508. Similarly, after UE 115skips transmission of a report at original reporting occasion 504, UE115 may add an additional PDCCH monitoring occasion or an additional SRoccasion at 509. The additional occasions may allow for additionalaperiodic report triggering if necessary.

FIG. 6 is a block diagram illustrating L1 reporting operations 60between UE 115 and network entity 105 configured to support adaptableconfiguration for periodic and semi-persistent L1 measurement reportingaccording to aspects of the present disclosure. Network entity 105transmits an L1 measurement report configuration via RRC signaling 600to UE 115. The L1 measurement report configuration configures UE 115with a number of reporting occasions at an L1 report period for eitherconfigured periodic or semi-persistent L1 measurement reporting.

A dynamic modification indication may be implicitly identified by UE 115and network entity 105 based on a set of predetermined rules. Accordingto the presently illustrated aspect, UE 115 and network 105 are aware ofpredetermined rules that indicates to UE 115 to multiplex an L1measurement report onto an uplink channel (e.g., dynamic grant PUSCH, aconfigured grant transmission occasion, PUCCH, etc.) that is scheduled apreconfigured time from an original reporting occasion. Thus, asillustrated, UE 115 transmits L1 measurement report at reportingoccasions 601 and 602. UE 115 and network entity 105 determine that anuplink channel 603 (e.g., dynamic grant PUSCH, configured granttransmission occasion, PUCCH, etc.) is available for UE 115 less than apreconfigured time, T_(m), from original reporting occasion 604. Basedon this information, UE 115 knows to multiplex the next L1 measurementreport onto uplink channel 603 and network entity 105 knows that the L1measurement report will be multiplexed onto uplink channel 603.

FIG. 7 is a block diagram illustrating L1 reporting operations 70between UE 115 and network entity 105 configured to support adaptableconfiguration for periodic and semi-persistent L1 measurement reportingaccording to aspects of the present disclosure. Network entity 105transmits an L1 measurement report configuration via RRC signaling 700to UE 115. The L1 measurement report configuration configures UE 115with a number of reporting occasions at an L1 report period for eitherconfigured periodic or semi-persistent L1 measurement reporting.

After UE 115 transmits an L1 measurement report at reporting occasion701, a modification request 702 occurs. Modification request 702corresponds to an explicit dynamic modification indication. Modificationrequest 702 may be transmitted by UE 115 or it may be transmitted bynetwork entity 105. In a first alternative aspect illustrated in FIG. 7, UE 115 transmits modification request 702 to network entity 105. Inorder to allow network entity 105 to receive and process the request ofmodification request 702, a predetermined rule known to UE 115 andnetwork entity 105 provides that when a request, such as modificationrequest 702, is made within a preconfigured time, T_(pr), from a nextreporting occasion, such as reporting occasion 703, the modificationwill not be applied until the next reporting occasion. Thus, withmodification request 702 within T_(pr) from reporting occasion 703, themodification within modification request 702 will be applied to originalreporting occasion 704, instead of reporting occasion 703. This allowsnetwork entity 105 to receive and process modification request 702.

In a second alternative aspect illustrated in FIG. 7 , network entity105 transmits modification request 702. In order to allow UE 115 toreceive and process the request of modification request 702, becausemodification request 702 is received within T_(pr) from reportingoccasion 703, UE 115 will apply the modification to original reportingoccasion 705 instead of to reporting occasion 703. T_(pr) may beconfigured based on the processing capabilities of UE 115.
